Right in the middle, so 2.5m along
Would the angle of repose be subtracted from the final angle? Or is it not relevant? I'm getting a final value of 82.032 degrees

That was supposed to be a table ^, but I can't seem to paste it here.

Homework Statement
A ladder of length 5 m is resting against a SMOOTH wall, its point of contact being just below a first floor window. The bottom of the ladder rests on the ground and the coefficient of friction between the ladder and the ground is 0.28
A person of mass 78 kg climbs the...
Ahh, I see now. That's helped actually - thanks.
Can you think of any improvements to the circuit that could be made? Up to now I've said perhaps use a different voltage which can be split more evenly across the circuit
Other than it not receiving current anymore, or a fault in the circuit components I'm not sure sorry.
Here is my circuit diagram though, would anybody be able to tell me how I should order a block diagram based on this?
The circuit blocks are:
Power supply, preset level of LDR, timer...
The question just asks why the time delay function, in particular, is necessary to serve 'that part of the circuit' that determinines incandescent light failure.
I don't actually know anything about 'that part of the circuit' and how it determines the failure, sorry. I'm a newbie to...
I'm not sure how I'd quantify that? Would this be the 'time constant' ? I've wrote the definition as:
'the measure of the inertia of a sensor and how fast it reacts to changes in input - the bigger the input change the slower the reaction to a change in input signal.'
Therefore would the time...
Is this why it's necessary for LEDs in a circuit to have resistors in series? The answer to this probably depends upon the type of circuit. This is the circuit I'm referring to on a breadboard:
Is it okay if I add to this thread with different questions that relate to the same circuit? (that I posted above)
If so my next problem is finding out why a time delay is needed to show that the incandescent light had failed. I've no idea about this so any hints or pointers would be great...
Thanks alot. 'Manufacturing', 'motorised' and 'industrial' search terms seem to be producing better webpages now. I need to:
- Provide Schematic of the chosen part
▪ Model the mechanical behaviour
▪ Explain the working principle
▪ Identify the different part of the system
(links, joints, gears...
Haha, I wish it was the amusement park ride!
So is it a mechanism that converts electrical power into rotational mechanical power, and vice versa? I assume it's comprised of gears, belts, links and joints as well as a motor of some sort?

This may sound like a ridiculous question, but I'm required to do a presentation on mechanical aspects of mechatronics - specifically explaining what a carousel is. However, the internet doesn't seem to know what one is...
